ABSTRACT

The invention relates to new phenyl-substituted cyclic ketoenols of the formula (I) in which 
     Het represents one of the groups ##STR1## wherein A, B, D, G, X, Y and Z have the meaning given in the description, several processes and intermediate products for their preparation and their use as pest control agents and herbicides.

The invention relates to new phenyl-substituted cyclic ketoenols, several processes and intermediate products for their preparation and their use as pest control agents and herbicides.

It has already been disclosed that certain phenyl-substituted cyclic ketoenols are active as insecticides, acaricides and/or herbicides.

Pharmaceutical properties have already been described for 3-acyl-pyrrolidine-2,4-diones (S. Suzuki et al. Chem. Pharm. Bull. 15 1120 (1967)). Furthermore, N-phenylpyrrolidine-2,4-diones have been synthesized by R. Schmierer and H. Mildenberger (Liebigs Ann. Chem. 1985, 1095). No biological activity has been described for these compounds.

EP-A-0 262 399 and GB-A-2 266 888 disclose compounds of similar structure (3-aryl-pyrrolidine-2,4-diones), of which, however, no herbicidal, insecticidal or acaricidal action has been disclosed. Known compounds which have a herbicidal, insecticidal or acaricidal action are unsubstituted, bicyclic 3-aryl-pyrrolidine-2,4-dione derivatives (EP-A-355 599 and EP-A-415 211) and substituted monocyclic 3-aryl-pyrrolidine-2,4-dione derivatives (EP-A-377 893 and EP-A-442 077).

Compounds which are furthermore known are polycyclic 3-arylpyrrolidine-2,4-dione derivatives (EP-A-442 073) and IH-arylpyrrolidine-dione derivatives (EP-A-456 063, EP-A-521 334, EP-A-596 298, EP-A-613 884, EP-A-613 885, DE 44 40 594, WO 94/01 997 and WO 95/01 358).

It is known that certain substituted Δ³ -dihydrofuran-2-one derivatives have herbicidal properties (cf. DE-A-4 014 420). The synthesis of the tetronic acid derivatives used as starting compounds (such as, for example, 3-(2-methyl-phenyl)-4-hydroxy-5-(4-fluorophenyl)-Δ³ -dihydrofuran-2-one) is likewise described in DE-A-4 014 420. Compounds of similar structure, without an insecticidal and/or acaricidal activity being mentioned, are known from the publication Campbell et al., J. Chem. Soc., Perkin Trans. 1, 1985, (8) 1567-76. 3-Aryl-Δ³ -dihydrofuranone derivatives having herbicidal, acaricidal and insecticidal properties are furthermore known from EP-A-528 156, EP-A 0 647 637 and WO 95/26345.

Certain phenyl-pyrone derivatives which are unsubstituted in the phenyl ring have already been disclosed (cf. A. M. Chirazi, T. Kappe and E. Ziegler, Arch. Pharm. 309, 558 (1976) and K.-H. Boltze and K. Heidenbluth, Chem. Ber. 91, 2849), no possible usefulness of these compounds as pest control agents being mentioned. Phenyl-pyrone derivatives which are substituted in the phenyl ring and have herbicidal, acaricidal and insecticidal properties are described in EP-A-588 137.

Certain 5-phenyl-1,3-thiazine derivatives which are unsubstituted in the phenyl ring have already been disclosed (cf. E. Ziegler and E. Steiner, Monatsh. 95, 147 (1964), R. Ketcham, T. Kappe and E. Ziegler, J. Heterocycl. Chem. 10, 223 (1973)), no possible use as pest control agents being mentioned for these compounds. 5-Phenyl-1,3-thiazine derivatives which are substituted in the phenyl ring and have a herbicidal, acaricidal and insecticidal action are described in WO 94/14 785.

However, the acaricidal and insecticidal activity and/or range of action and the plant tolerance of these compounds, in particular with respect to crop plants, is not always adequate.

The compounds of the formula (I) can be in the form of geometric and/or optical isomers or isomer mixtures of varying composition, also depending on the nature of the substituents, and these can optionally be separated in the customary manner. The present invention relates both to the pure isomers and to the isomer mixtures, their preparation and use and compositions comprising them. For simplicity, however, reference is always made below to compounds of the formula (I), although this means both the pure compounds and, where appropriate, also mixtures with different contents of isomeric compounds.

The compounds of the formula (I-4) can be present in the two isomeric forms of the formulae (I-4)_(a) and (I-4)_(b), depending on the position of the substituent G ##STR9## which is illustrated by the broken line in the formula (I-4).

The compounds of the formulae (I-4)_(a) and (I-4)_(b) can be present both in the form of mixtures and in the form of their pure isomers. Mixtures of the compounds of the formulae (I-4)_(a) and (I-4)_(b) can be separated, where appropriate, by physical methods in a manner known per se, for example by chromatographic methods.

For reasons of better clarity, in each case only one of the possible isomers is mentioned below. This does not mean that the compounds cannot be present, where appropriate, in the form of the isomer mixtures or in the other particular isomeric form.

Incorporating the various meanings (a), (b), (c), (d), (e), (f) and (g) of the group G, the following main structures (I-4-a) to (I-4-g) result if Het represents the group (4) ##STR10## wherein A, D, E, L, M, X, Y, Z, R¹, R², R³, R⁴, R⁵, R⁶ and R⁷ have the abovementioned meanings.

Bristle-tails such as Lepisma saccharina.

Industrial materials in the present connection are to be understood as meaning non-living materials, such as, preferably, plastics, adhesives, sizes, papers and cards, leather, wood and processed wood products, and lacquers and paints.

Material to be preserved from insect damage which is quite particularly preferred is wood and processed wood products.

Wood and processed wood products which can be protected by the agents according to the invention or mixtures comprising these are to be understood as meaning, for example: building timber, wooden beams, railway sleepers, bridge components, boat gangplanks, wooden vehicles, crates, pallets, containers, telegraph masts, wood lagging, wooden windows and doors, plywood, chipboards, joinery or wood products used quite generally in house construction or building joinery.

The active compounds can be used as such or in the form of concentrates or generally customary formulations, such as powders, granules, solutions, suspensions, emulsions or pastes.

The formulations mentioned can be prepared in a manner known per se, for example by mixing the active compounds with at least one solvent or diluent, emulsifier, dispersing agent and/or binder or fixing agent, water repellant, optionally siccatives and UV stabilizers, and if appropriate dyestuffs and pigments, as well as other processing auxiliaries.

The insecticidal compositions or concentrates used for preservation of wood and derived timber products comprise the active compound according to the invention in a concentration of 0.0001 to 95% by weight, in particular 0.001 to 60% by weight.

The amount of composition or concentrate employed depends on the nature and the occurrence of the insects and on the medium. The optimum amount employed for the use can in each case be determined by a series of tests. In general, however, it is sufficient to employ 0.0001 to 20% by weight, preferably 0.001 to 10% by weight, of the active compound based on the material to be preserved.

The solvent and/or diluent used is an organochemical solvent or solvent mixture and/or an oily or oil-like organochemical solvent or solvent mixture of low volatility and/or a polar organochemical solvent or solvent mixture and/or water and, if appropriate, an emulsifier and/or wetting agent.

Oily or oil-like solvents having an evaporation number above 35 and a flash point above 30° C., preferably above 45° C., are preferably employed as organochemical solvents. Corresponding mineral oils or aromatic fractions thereof or solvent mixtures containing mineral oil, preferably white spirit, petroleum and/or alkylbenzene, are used as such water-insoluble, oily and oil-like solvents of low volatility.

Mineral oils having a boiling range from 170 to 220° C., white spirit having a boiling range from 170 to 220° C., spindle oil having a boiling range from 250 to 350° C., petroleum or aromatics having a boiling range from 160 to 280° C., terpentine oil and the like are advantageously employed.

In a preferred embodiment, liquid aliphatic hydrocarbons having a boiling range from 180 to 210° C. or high-boiling mixtures of aromatic and aliphatic hydrocarbons having a boiling range from 180 to 220° C. and/or spindle oil and/or monochloronaphthalene, preferably α-monochloronaphthalene, are employed.

The organic oily or oil-like solvents of low volatility having an evaporation number above 35 and a flash point above 30° C., preferably above 45° C., can be replaced in part by organochemical solvents of high or medium volatility, provided that the solvent mixture likewise has an evaporation number above 35 and a flash point above 30° C., preferably above 45° C., and that the insecticide/fungicide mixture is soluble or can be emulsified in this solvent mixture.

According to a preferred embodiment, some of the organochemical solvent or solvent mixture is replaced by an aliphatic polar organochemical solvent or solvent mixture. Aliphatic organochemical solvents containing hydroxyl and/or ester and/or ether groups, such as, for example, glycol ethers, esters or the like, are preferably used.

Organochemical binders which are the synthetic resins and/or binding drying oils which are water-dilutable and/or soluble or dispersible or emulsifiable in the organochemical solvents employed and are known per se, in particular binders consisting of or comprising an acrylate resin, a vinyl resin, for example polyvinyl acetate, polyester resin, polycondensation or polyaddition resin, polyurethane resin, alkyd resin or modified alkyd resin, phenolic resin, hydrocarbon resin, such as indene-coumarone resin or silicone resin, drying plant and/or drying oils and/or binders which dry by physical means and are based on a naturally occurring and/or synthetic resin.

The synthetic resin used as the binder can be employed in the form of an emulsion, dispersion or solution. Bitumen or bituminous substances can also be used as binders in an amount of up to 10% by weight. In addition, dyestuffs, pigments, water-repellant agents, odour correctants and inhibitors or corrosion prevention agents and the like which are known per se can be employed.

Preferably, according to the invention, the composition or concentrate comprises at least one alkyd resin or modified alkyd resin and/or one drying plant oil as an organochemical binder. Alkyd resins having an oil content of more than 45% by weight, preferably 50 to 68% by weight, are preferably used according to the invention.

All or some of the binder mentioned can be replaced by a fixing agent (mixture) or a plasticizer (mixture). These additives are intended to prevent evaporation of the active compounds and crystallization or precipitation They preferably replace 0.01 to 30% of the binder (based on 100% of the binder employed).

The plasticizers originate from the chemical classes of phthalic acid esters, such as dibutyl, dioctyl or benzyl butyl phthalate, phosphoric acid esters, such as tributyl phosphate, adipic acid esters, such as di-(2-ethylhexyl) adipate, stearates, such as butyl stearate or amyl stearate, oleates, such as butyl oleate, glycerol ethers or higher molecular weight glycol ethers, glycerol esters and p-toluenesulphonic acid esters.

Fixing agents are based chemically on polyvinyl alkyl ethers, such as, for example, polyvinyl methyl ether, or ketones, such as benzophenone or ethylenebenzophenone.

Water in particular is also a possible solvent or diluent, if appropriate mixed with one or more of the abovementioned organochemical solvents or diluents, emulsifiers and dispersing agents.

Particularly effective wood preservation is achieved by impregnation processes on a large industrial scale, for example vacuum, a double vacuum or pressure processes.

If appropriate, the ready-to-use compositions can also comprise other insecticides, and if appropriate also one or more fungicides.

Possible additional admixing partners are, preferably, the insecticides and fungicides mentioned in WO 94/29 268. The compounds mentioned in this document are an express constituent of the present application.

Especially preferred admixing partners can be insecticides, such as chlorpyriphos, phoxim, silafluofin, alphamethrin, cyfluthrin, cypermethrin, deltamethrin, permethrin, imidacloprid, NI-25, flufenoxuron, hexaflumuron and triflumuron, and fungicides, such as epoxyconazole, hexaconazole, azaconazole, propiconazole, tebuconazole, cyproconazole, metconazole, imazalil, dichlorfluanid, tolylfluanid, 3-iodo-2-propinyl butylcarbamate, N-octyl-isothiazolin-3-one and 4,5-dichloro-N-octylisothiazolin-3-one.

Example (I-1-b-1) ##STR127##

1.13 ml (0.015 mol) of acetyl chloride in 5 ml of absolute methylene chloride are added to 4.5 g (0.015 mol) of the compound according to Example (I-1-a-1) and 2.1 ml (15 mmol) of triethylamine in 70 ml of absolute methylene chloride at 0 to 10° C. The mixture is stirred at room temperature until, according to monitoring by thin layer chromatography, the reaction has ended. For working up, the mixture is washed twice with 50 ml of 0.5 N sodium hydroxide solution, dried over magnesium sulphate and evaporated. The crude product is recrystallized from MTB ether/n-hexane.

Yield: 3.4 g (66% of theory), melting point: 209° C.

Example II-1 ##STR131##

17.5 g of the compound according to Example (XXIX-1) in about 100 ml of methylene chloride are cautiously added dropwise to 30.3 g (0.308 mol) of concentrated sulphuric acid at 30 to 40° C. and the mixture is stirred at this temperature for 2 hours. 41 ml of absolute methanol are then added dropwise such that an internal temperature of about 40° C. is established, and the mixture is stirred at 40 to 70° C. for a further 6 hours.

For working up, the mixture is poured onto 0.29 kg of ice, extracted with methylene chloride, washed with aqueous sodium bicarbonate solution, dried and evaporated. The crude product is purified by column chromatography over silica gel using the mobile phase methylene chloride/ethyl acetate 2:1.

Yield: 13.1 g (67% of theory), melting point: 147° C.

Example (II2) ##STR132##

40.9 g (0.23 mol) of 2,4,5-trimethylphenylacetic acid and 33.6 ml (0.461 mol) of thionyl chloride are stirred at room temperature for 30 minutes and then at 50° C. until the evolution of gas has ended. Excess thionyl chloride is removed at 50° C. in vacuo. 50 ml of absolute toluene are then added and the mixture is evaporated again. The residue is taken up in 100 ml of absolute THF (solution 1).

Solution 1 is added to 47.9 g of methyl cis-4-methylcyclohexylamine-1-carboxylate and 64.6 ml (0.460 mol) of triethylamine in 600 ml of absolute THF at 0 to 10° C. and the mixture is then stirred at room temperature for 1 hour. It is then filtered with suction, washed with absolute THF and evaporated. The residue is taken up in methylene chloride and the mixture is washed with 0.5 N HCl, dried and evaporated. The crude product is purified by column chromatography over silica gel using methylene chloride/ethyl acetate 7:1.

Yield: 25 g (32% of theory), melting point: 158° C.

Example (XXIX-1) ##STR134##

Starting from 17.8 g of 2,4,5-trimethylphenylacetic acid, solution 1 is prepared as in Example (II-2).

Solution 1 is added dropwise to 16.8 g of 1-amino-tetrahydropyran-1-carboxylic acid nitrile (70% pure) and 16.8 ml (0.12 mol) of triethylamine in 150 ml of absolute THF at 0 to 10° C. and the mixture is stirred at room temperature for a further hour. It is then evaporated, the residue is taken up in methylene chloride and the mixture is washed with 0.5 N HCl, dried and evaporated. The crude product is recrystallized from MTB ether/n-hexane.

Yield: 17.5 g (61% of theory), melting point: 156° C.

Example (I-2-a-1) ##STR135##

8.42 g (75 mmol) of potassium tert-butylate are initially introduced into 50 ml of dimethylformamide, a solution of 16.6 g (50 mmol) of 1-ethyloxycarbonylcyclohexyl 2,4,5-trimethyl-phenylacetate according to Example (III-1) in 50 ml of dimethylformamide is added dropwise at 0 to 10° C. and the mixture is stirred overnight at room temperature.

For working up, the reaction mixture is added dropwise in 500 ml of ice-cold 1 N HCl and the product which has precipitated out is filtered off with suction, washed with water and dried in a vacuum drying cabinet. For further purification, the crude product is boiled up further with n-hexane/acetone.

Example (I-2-b-1) ##STR137##

2.86 g (10 mmol) of the compound according to Example I-2-a-1 are initially introduced into 40 ml of methylene chloride, 1.52 g (15 mmol) of triethylamine are added, a solution of 1.57 g (13 mmol) of pivaloyl chloride in 40 ml of methylene chloride is added dropwise, while cooling with ice, and the mixture is subsequently stirred at room temperature for 1 to 2 hours. For working up, the mixture is washed successively with 10% strength citric acid, IN NaOH and NaCl solution and the organic phase is dried over MgSO₄ and evaporated. For further purification, the crude product is stirred further with a little petroleum ether.

Example (III-1) ##STR139##

8.9 g (50 mmol) of 2,4,5-trimethyl-phenylacetic acid are initially introduced into 50 ml of toluene, 11.9 g (100 mmol) of thionyl chloride are added and the mixture is stirred at 80° C. until the evolution of hydrogen chloride has ended and is then evaporated. The crude acid chloride is boiled in 50 ml of toluene together with 8.6 g (50 mmol) of ethyl 1-hydroxy-cyclohexanecarboxylate overnight and the mixture is then evaporated.

Yield: 18.6 g (quantitative) of 1-ethoxycarbonyl-cyclohexyl 2,4,6-trimethylphenylacetate as a colourless oil.

The following compounds of the formula (III) are obtained analogously and in accordance with the general instructions for preparation:

Example H

Test with Fly Larvae / Development-Inhibiting Action

Test animals: All larval stages of Lucilia cuprina (OP-resistant) [pupae and adults (without contact with the active compound)]

Solvent: 35 parts by weight of ethylene glycol monomethyl ether 35 parts by weight of nonylphenol polyglycol ether

To produce a suitable formulation, 3 parts by weight of active compound are mixed with seven parts of the abovementioned solvent/emulsifier mixture and the emulsion concentrate thus obtained is diluted with water to the particular desired concentration.

30 to 50 larvae per concentration are introduced onto horse-meat (1 cm³), in glass tubes, onto which 500 μl of the dilution to be tested are pipetted. The glass tubes are placed in plastic beakers, the base of which is covered with beach sand, and are stored in a climatically controlled room (26° C.±1.5° C., 70% relative humidity ±10%). The action is checked after 24 hours and 48 hours (larvicidal action). After emergence of the larvae (about 72 hours), the glass tubes are removed and perforated plastic lids are placed on the beakers. After 11/2 times the development period (hatching of the control flies), the flies which have hatched and the pupae/pupae cases are counted.

The criterion for the action is the onset of death among the treated larvae after 48 hours (larvicidal effect) or the inhibition of hatching of adults from the pupae or the inhibition of pupae formation. The criterion for the in vitro action of a substance is the inhibition of flea development or a halt in development before the adult stage. 100% larvicidal action means that all the larvae have died after 48 hours. 100% development-inhibiting action means that no adult flies have hatched.

In this test, for example, the compound according to Preparation Example I-4-a-1 caused an action of 100% at an active compound concentration of, for example, 1000 ppm.

Example I

Test with Boophilus Microplus Resistant/SP-Resistant Parkhurst Strain

Test animals: Adult satiated females

Solvent: Dimethyl sulphoxide

20 mg of active compound are dissolved in 1 ml of dimethyl sulphoxide, and lower concentrations are prepared by dilution in the same solvent.

The test is carried out as a 5-fold determination. 1 μl of the solutions is injected into the abdomen and the animals are transferred to dishes and kept in a climatically controlled room. The action is determined via the inhibition of oviposition. 100% means that no tick has laid.

In this test, for example, the compounds according to Preparation Examples I-4-a-1 and I-4-b-1 had an action of 100% at an active compound concentration of, for example, 20 μg per animal.
